Non-invasive malaria test -Future of Malaria diagnosis
A 25-year-old Ugandan computer scientist has won a prestigious engineering prize for a non-invasive malaria test kit. Brian Gitta came up with a bright idea of developing a malaria test that would not need blood samples or specialized laboratory technicians after he was languished by fever and frustrated by delays in diagnosis of his illness.
For developing the reusable test kit known as Matibabu, he was awarded the Africa Prize for Engineering Innovation. The award by the Royal Academy of Engineering in Britain comes with £25,000 ($32,940).
Gitta and five colleagues, all trained in computer science or engineering, developed an affordable, bloodless test that does not need a specialist to operate. The test will be suitable for use in Africa's rural areas, where most cases of malaria occur because it will not depend on sending blood samples to a distant laboratory.
Malaria is the biggest killer in Africa, and the sub-Saharan region accounts for about 80 percent of the world's malaria cases and deaths. According to the latest World Malaria Report, released late last year, cases rose to 216 million in 2016, up from 211 million cases in 2015. Malaria deaths fell by 1,000, to 445,000.
The mosquito-borne disease is a challenge to prevent, with increasing resistance reported to both drugs and insecticides.
The new malaria test kit works by shining a red beam of light onto a finger to detect changes in the shape, color, and concentration of red blood cells, all of which are affected by malaria. The results are sent within a minute to a computer or mobile phone linked to the device.
A Portugal-based firm has been contracted to produce the components for Matibabu, the Swahili word for "treatment."
"It's a perfect example of how engineering can unlock development - in this case by improving health care," Rebecca Enonchong, Africa Prize for Engineering Innovation judge, said in a statement. "Matibabu is simply a game changer."
Others are also working to fill the need for quicker, easier malaria tests. There are over 200 rapid diagnostic test products for malaria on the market, according to the WHO.
"It excites me as a clinician," said Medard Bitekyerezo, a Ugandan physician who chairs the National Drug Authority. "I think the National Drug Authority will approve it."
The government should invest in the project so that its developers don't struggle financially, he added. The unit cost of the latest prototype is about $100.
Despite the optimism, Gitta has found a hurdle he didn't anticipate: Some patients are skeptical of unfamiliar technology.
"The doctors will tell you that some people will not leave the hospital until their children have been pricked, and until they have been given anti-malaria drugs and painkillers, even if the kid is not sick," he said.
"We think we are developing for hospitals first so that people can first get attached to the brand, and gain the trust of patients over time."
The fifth-generation prototype of Matibabu, with an accuracy rate of 80 percent, is still a work in process. Gitta and his group aim to refine the device until it achieves an accuracy rate exceeding 90 percent.
Matibabu has yet to be formally subjected to all the necessary clinical trials under Ugandan safety and ethics regulations.
